Superciliaris Meng, Qin & Wang (in Zhang et al. 2020): 296.

Type species

Superciliaris reticulatus Meng, Qin & Wang, 2020 .

Diagnosis

Head, pronotum, mesonotum, and forewings finely shagreened by punctation. Metope (frons) wide, with lateral margins nearly straight or slightly converging above eyes and foliated below eyes hanging over the pedicels (Fig 4B, D, F). Metopoclypeal suture nearly straight, deep. Pedicel globular. Rostrum distinctly protruding beyond hind coxae; 3 rd segment long, nearly as long as 2 nd one, narrowing apically. Eyes 0.5 × as wide as coryphe (vertex) (in dorsal view) (Figs 1A, 2A, 3A). Paradiscal fields of pronotum very narrow behind eyes. Paranotal lobes of pronotum triangular-shaped, with strongly producing lower angle (Fig. 4A). Scutellum depressed basally. Tegulae narrow, with elongate depression (Fig. 4E, G). Forewings wide, with reticulate venation, without hypocostal plate, claval suture invisible. Forewing costal margin strongly protruding below eyes (in lateral view) (Fig. 4C, E, G). Hind wings rudimentary. Male anal tube with long and narrow column. Male pygofer elongate vertically. Apical aedeagal process long and narrow, pointed, well visible above upper phallobase margins as two filaments (Figs 5B, 6B, 7A). Aedeagus with pair of ventral hooks directed basally, nearly straight or strongly curved. Gonopore apical.
